SAMUEL THOMAS HARVEY, OF BALTIMORE, MARYLAND.

STOVE.

Specification of Letters Patent No. 31,716, dated March 19, 1861.

T 0 all 'whom 'it may concern:

Be it known that I, SAMUEL THOMAS HARVEY, of Baltimore, in the State of Maryland, have invented a new Arrangement of Stove Viewed as a lVhole; and I do hereby declare that` the following is a full and eX- act description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in the arrangment of a stove, in such manner that railroad cars can be effectually heated, by consuming either wood or coal, with safety, through an aperture made in the floor, the Stove being attached to, and securely suspended beneath, thus obviatig the present obstruction in the interior, caused by the Stoves now in use.

" To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A, A, A, in all 'the views and sections in `dicate the :Hue for the exit of smoke and gases; B, B, B, water chamber; C, C, C, register of any suitable construction to regulate the admission of heat; D, D, D, plate of Zinc or other suitable material; E, E, E, air chamber surrounding upper part of furnace andsupport of furnace when suspended; F, F, F, perforated plate; G, Gr, G, furnace or stove proper; H, H, H, crank for shaking grate I, I, I; K, K, K, pinion for turning and regulating damper L, L, L; M, M, M, holes in bottom of furnace for the admission of air, opened and closed by damper L; N, N, flange or suspension circle to support the furnace when attached to the aii chamber B; O, opening in the bottom of furnace to empty its contents, opened and closed by a door with hinge and latch attached; P, P, Vopening for escape of evaporation from water chamber. The opening is formed by the inner partition of water chamber B, being made lower than the outer wall of drum which is firmly attached to the car Hoor; Q a pipe for admission of water into chamber B. The pipe is attached to the drum, and passes through the Hoor, so that the chamber B can be supplied with water by` the temporary use of a funnel, the end of pipe to be closed when not required for usc by suitable stopper. The drum when attached to its designed place, forms two compartments, one between the furnace and inner partition, which arrests the heat of furnace, which ascends upward through E and C, into the car; between the inner partition and outer' wall of drum another chamber is formed water tight, which when filled, answers the double purpose of arresting heat and supplying vapor, which passes through the opening at P. This arrangement of drum I have termed the double drum and think it indispensable for the purposes above named, the consumption of coal, has been considered and its bad effects thus provided for by the arrangement of water chamber for purposes of evaporation, and admission of fresh air through the openings atR, It, formed by a vacancy between the bottom of drum and furnace, evaporation of 'water and fresh air are both necessary to health when coal is consumed.

IVhat I claim as my invention, and desire to secure by Letters Patent, is-

The combination of the water chamber, air chamber, stove, and register, when the several parts are constructed and arranged in the manner and for the purposes specified.
